With the rapid development of networked information technology, the advantages of Power over Ethernet (PoE) are gradually becoming well-known to everyone. Only one Ethernet cable is needed, and PoE can provide power to network devices while also transmitting data, eliminating wiring and saving costs and space. The devices can be moved freely, and the system deployment is flexible.
With the increasing scale of network systems and the maturity of PoE switch applications, users have higher requirements for PoE switches: intelligence, stability, flexibility, efficiency, and ease of management, which have become the basic demands for PoE switches.
The chief editor of the White Paper on Power over Ethernet (PoE) Technology and Applications and the Engineering Technical Standards for Power over Ethernet (PoE) Systems has been committed to the research and application of innovative PoE technologies for over 10 years, and has applied these technologies to PoE switch products to provide customers with a better application experience.
- Support IEEE802.3bt standard
The PoE standard has evolved and currently mainly includes IEEE 802.3 af, IEEE 802.3 at and IEEE 802.3 bt are three standards. The 802.3bt standard is backward compatible with 802.3at and 802.3af, and can extend power up to 90W. Due to breaking through power limitations, BT PoE greatly expands the application scenarios of PoE technology and supports more terminal devices.
PoE switches support IEEE 802.3 af/at/bt, and products that support the bt PoE standard have covered 90W bt PoE switches, 90W bt PoE network repeaters, 90W bt PoE power supplies, and other products, forming a complete solution that is widely used in various industries such as smart buildings, smart retail, education, healthcare, transportation, and energy.
- PoE Watchdog's featured self-healing technology
The PoE switch with the self-healing function of PoE Watchdog can easily solve the problem of network camera crashes and restarts in monitoring systems. After enabling this function, the system can automatically detect the front-end camera 24 hours a day. If the camera has no data output, it is judged that the camera has crashed. The front-end camera can be restarted through PoE power outage to solve the camera crash problem. No manual operation is required, providing timely and reliable solutions for the later operation and maintenance of the project.
- Permanent PoE function
Permanent PoE has the ability to restart switches and provide continuous power to devices connected to PoE. Generally speaking, restarting a switch can cause temporary power outages to ports, resulting in a complete restart of all connected devices, which is not allowed in some scenarios. Permanent PoE solves this problem by providing constant power to external devices through PoE ports, even when the power switch is restarted or the system is upgraded.
Switch products that use permanent PoE technology, such as the UTOP 2000W 24 port full gigabit BT switch UTP5328S-PSD2000, can provide uninterrupted power supply for connected power receiving devices (PDs) even when the switch is restarted.
